ComicZeal costs $2.99 in the itunes app store and its worth every penny. It comes with some free comics but there kinda bland and not the ones you want to read. That's where the desktop application comes in which is called ComicZeal Sync. As long as your Iphone/Ipod Touch is on the same wireless network you can convert cbr,cbz,rar and zip into cbi files which can be put on your Ipod wirelessly.
